What am I missing? - pragmatic - 11-04-2012
So I'm running some bruteforce attacks with a system using 8 x 7970s and I can't seem to get my utilization up to full speed.
For instance:
$ ./oclHashcat-plus64.bin -a 3 -m 1000 -n 160 --gpu-loops=1024 --remove tobecracked ?a?a?a?a?a?a?a?a
oclHashcat-plus v0.09 by atom starting...

Using -lite gets them all going 99% just fine, but for plus it seems to ceiling out around 77-82%.
Any thoughts/suggestions?

looks like you're using the wrong driver. need to use catalyst 12.8. if you're going to use catalyst 12.10, then you need to stop x11 and run hashcat as root.

Thanks, I'll try it!
RE: What am I missing? - pragmatic - 11-11-2012
So I'm trying to run 12.10 without x11 as root but now I'm getting the dreaded "ERROR: clGetDeviceIDs() -1"
# ./oclHashcat-lite64.bin -n 800 --gpu-loops 1024 -1 ?l?d?s?u --gpu-temp-disable --outfile-watch 0 --restore-timer 0 --runtime 10 --pw-min 8 -m 0 ffffffffffffffffffffffffffffffff ?1?1?1?1?1?1?1?1?1
ERROR: clGetDeviceIDs() -1
aticonfig --lsa correctly shows all of my cards.
Any suggestions?

Is fglrx loaded? What does clinfo show?

RE: What am I missing? - epixoip - 11-11-2012
grepping through dmesg actually only proves that it was loaded at one time since last reboot, it doesn't show that it's still loaded. for future reference, ''grep fglrx /proc/modules'' or ''lsmod | grep fglrx'' would have been preferred. but since clinfo is showing your devices, it looks like it is in fact loaded.
and oclhashcat still won't run? sounds like you may have more than one libOpenCL installed. do you by chance have vcl installed on the system as well?
RE: What am I missing? - pragmatic - 12-04-2012
Sorry, I haven't been able to work on this for a while so I couldn't get more information until now.
Just for the sake of completeness:
# grep fglrx /proc/modules
fglrx 4740767 0 - Live 0xffffffffa023a000 (P)
And I don't have vcl installed.
Any help would be greatly appreciated, and can now be acted on quickly.

RE: What am I missing? - atom - 12-08-2012
Please do not use any other version than 12.8. Everything above is more or less broken.
RE: What am I missing? - pragmatic - 12-09-2012
Will do. I'm excited about getting away from X but obviously having it work is more important. Thanks!
